Smoky Quartz on Adularia Quartz is a hard (Mohs =7), crystalline mineral composed of silicon and oxygen (SiO2); it is the most abundant mineral found on the earth’s surface. Quartz can be found as massive, non-crystalline, opaque white deposits known as milky quartz, or as clear hexagonal crystals known as “rock crystal” varying in size from very small to very large. Quartz crystal faces always intersect at a 600 angle regardless of size or overall shape of the crystal. They can be found in virtually every color and different names such as amethyst, citrine, rose quartz and smoky quartz are used to describe the crystal depending on color. Herkimer “Diamond” is the name given to exceptionally clear, well formed crystals from Herkimer, New York. The various colors are imparted by impurities in the crystalline structure. Impurities in the microcrystalline varieties are also known by many names depending on the impurity (color and transparency), such as agate, jasper, chalcedony, flint, tiger eye and onyx to name a few. Quartz breaks with a distinctive conchoidal fracture with the edge of the flake being exceedingly sharp. Chalcedony and flint were often used to make arrow heads and spear points. It is the primary constituent of sand found at the beach, in the river, and in the desert. Smoky quartz is created when quartz crystals are exposed to radiation and range from a very light smoky coloring to black depending on the amount of radiation to which the crystal has been exposed. It is the natural gem of Scotland where it was mined by the Celts in the Scottish highlands. These stones eventually became popular decorations for Scottish jewelry, kilt pins, and on the handles the Scottish dagger sgian dubh, a “sock knife” which is still part of a proper kilted dress uniform. Flat panes of smoky quartz were used as sun glasses in 12th century China. Adularia is a variety of orthoclase feldspar with the formula (KAlSi3O8 ) a potassium aluminum silicate. It commonly forms colorless, glassy, prismatic, twinned crystals in low-temperature veins of granites and in cavities in crystalline schist. When it shows opalescence it is called moonstone. Uses Quartz is used in glass making, abrasives, foundry sand, and the colored varieties are often cut into gemstones. Rock crystal is often is most often appreciated for its shape and clarity. Quartz is chemically inert in contact with most substances and has electrical properties and heat resistance that make it valuable in electronics. One of the most amazing properties of quartz is the ability of its crystals to vibrate at precise frequencies. They are so precise the crystals can be used to make extremely accurate time-keeping instruments and equipment that can transmit radio and television signals with precise and stable frequencies. The tiny devices used for these purposes are known as “crystal oscillators.” Today, billions of quartz crystals are used to make oscillators for watches, clocks, radios, televisions, electronic games, computers, cell phones, electronic meters, and GPS equipment. Optical-grade quartz crystals are used to make specialized lenses, windows and filters used in lasers, microscopes, telescopes, electronic sensors, and scientific instruments. The material of beach sand is now the material of the world’s most advanced electronic devices. Today nearly all quartz crystals used in industry are lab grown where the amount of impurities can be tightly controlled. The only use for adularia is when it has opalescence and is known as moonstone which is used for jewelry. Meaning Smoky quartz is one of the premier grounding stones and can help even the spaciest individuals to get grounded so they can function as human beings. It can absorb and transmute almost unlimited amounts of negative energy. When worn helps in drawing the ethereal into manifestation.
